[0002] Wire rope, a rope made of multiple strands of fine steel wire, is widely used in various mechanical equipment and engineering fields. It can withstand high tensile forces and exhibits excellent wear and fatigue resistance. Therefore, it is widely used in machinery and equipment such as cranes, elevators, conveyor belts, and cable cars, as well as in various industries such as construction, transportation, mining, and metallurgy. Hoisting wire rope, also known as lifting wire rope, is used to lift heavy objects and is primarily used in machinery and equipment such as cranes, elevators, and conveyor belts. To ensure safety and reliability, hoisting wire ropes must meet certain performance requirements, such as sufficient strength, good wear and fatigue resistance, etc.

[0003] Existing hoisting wire ropes are made of multiple strands of fine steel wire twisted together. When used, hoisting wire ropes are used to lift heavy objects. However, existing hoisting wire ropes are simply made of multiple strands of steel wire twisted together. The wear resistance of the wire ropes is determined by the wear resistance of the steel wires, which is average. Furthermore, the corrosion resistance and fracture resistance of the wire ropes are also related to the characteristics of the steel wires themselves, resulting in poor performance.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figures 1-4As shown, a steel wire rope with a multi-layer composite structure includes an intermediate basic component, which is composed of an intermediate buffer layer 1, an internal pressure-resistant layer 2, a supporting inner core 3 and a circular hole 4. The intermediate buffer layer 1 in the intermediate basic component is provided with an external winding structure 5, and the external winding structure 5 includes an external intermediate body 501 and a composite component 502. The internal pressure-resistant layer 2 is installed inside the intermediate buffer layer 1, and a mounting hole is provided inside the internal pressure-resistant layer 2. The supporting inner core 3 is fixedly arranged in the mounting hole on the internal pressure-resistant layer 2. The circular hole 4 is opened on the supporting inner core 3, and the circular holes 4 are distributed in an annular array on the supporting inner core 3. The external winding structure 5 is distributed in an annular array on the outer surface of the intermediate buffer layer 1, and the external winding structure 5 is wound on the outer surface of the intermediate buffer layer 1. By setting the intermediate buffer layer 1, the internal pressure-resistant layer 2, the supporting inner core 3 and the circular hole 4, basic support is provided inside the entire steel wire rope, which can increase the overall strength of the steel wire rope and ensure the service life of the steel wire rope. The setting of the circular hole 4 can reduce the weight of the entire steel wire rope without affecting the use effect of the steel wire rope.

[0019] During the production and preparation of the lifting wire rope, the external winding structure 5 and the intermediate basic component are manufactured separately. When the intermediate basic component is manufactured, an internal pressure-resistant layer 2 is set on the outer surface of the supporting inner core 3, and circular holes 4 distributed in a ring array are set on the supporting inner core 3. An intermediate buffer layer 1 is set on the outer surface of the internal pressure-resistant layer 2. After the external winding structure 5 is manufactured, multiple external winding structures 5 are wound onto the outer surface of the intermediate buffer layer 1 in the intermediate basic component to ensure that the external winding structure 5 is evenly wound and distributed, thereby completing the setting of the entire lifting wire rope. When using the lifting wire rope, the lifting wire rope is used to support and lift heavy objects. At this time, the intermediate basic component cooperates with the external winding structure 5 to provide basic support effect. During use, the supporting inner core 3 ensures that the wire rope has good basic support, and the circular holes 4 reduce the weight of the wire rope without affecting the normal use of the wire rope. The intermediate buffer layer 1 and the internal pressure-resistant layer 2 protect the supporting inner core 3, thereby ensuring the stable use of the entire wire rope.

[0020] According to the above embodiment, the composite component 502 is wound around the outer surface of the outer intermediate body 501, and the composite component 502 is distributed in a ring array on the outer intermediate body 501. The composite component 502 includes a protective wear-resistant layer 5021, an anti-corrosion layer 5022, an anti-fracture connecting layer 5023 and a steel wire body 5024. The anti-corrosion layer 5022 is arranged inside the protective wear-resistant layer 5021, and the protective wear-resistant layer 5021 is fixedly connected to the anti-corrosion layer 5022. A cavity is provided inside the anti-corrosion layer 5022, and the anti-fracture connecting layer 5023 is arranged inside the steel wire body 5024. Installed in the cavity inside the anti-corrosion layer 5022, the steel wire body 5024 is embedded in the anti-fracture connecting layer 5023, and the steel wire body 5024 is fixedly connected to the anti-fracture connecting layer 5023. The external winding structure 5 is formed by the external intermediate 501 and the composite component 502. The composite component 502 provides a multi-layer composite structure, which greatly improves the wear resistance and anti-fracture effect of the wire rope, increases the tensile strength and service life of the wire rope, further improves the use effect of the entire wire rope, and reduces the use cost to a certain extent.

[0021] When setting the external winding structure 5, an anti-fracture connecting layer 5023 is coated on the outer surface of the steel wire main body 5024, and an anti-corrosion layer 5022 is coated on the outer surface of the anti-fracture connecting layer 5023. Finally, a protective wear-resistant layer 5021 is set on the outer surface of the anti-corrosion layer 5022. After the multi-layer structure composite component 502 is set, multiple composite components 502 are wound onto the outer surface of the external intermediate body 501 to ensure that the composite components 502 are distributed in a circular array on the external intermediate body 501. After the entire external winding structure 5 is set, the external winding structure 5 is evenly wound onto the intermediate basic component to complete the manufacture of the entire steel wire rope. In the process of using the steel wire rope, the external intermediate body 501 is the outer The internal winding structure 5 provides basic support to ensure that the external winding structure 5 has a good use effect. The protective wear-resistant layer 5021 is located on the outermost side of the wire rope and is in direct contact with the external structure. It can play a wear-resistant role and ensure the wear resistance of the wire rope. The anti-corrosion layer 5022 plays a corrosion-resistant role and ensures that the internal steel wire body 5024 will not be corroded, thereby increasing the service life of the wire rope. The anti-fracture connection layer 5023 provides higher strength and increases the tensile effect of the entire wire rope, so that the wire rope will not undergo large deformation under the action of tension, reducing the impact of tensile stress, and to a certain extent increasing the service life of the wire rope and saving costs.
